registered in accordance with Section 1.6(c) to be listed for sale on NASDAQ concurrently with such registration. The Stockholder Representative shall furnish to Parent such information regarding the Company Stockholders as Parent may request in writing and as shall be required in connection with any registration referred to in this Section 1.6(c). All registration expenses incurred in connection with the registration described in Section 1.6(c) shall be borne by Parent.

(d) Stockholder Approval. If required by applicable NASDAQ National Market Rules, Parent may seek stockholder approval prior to the issuance of Parent Common Stock as Contingent Consideration in accordance with applicable Law and Parent’s certificate of incorporation and bylaws; provided, however, that the receipt of such stockholder approval shall not be a condition to Parent’s obligations under this Section 1.6.

(e) Company Stockholders’ Acknowledgement. By their approval of the transactions contemplated by this Agreement, the Company Stockholders acknowledge and agree that the receipt of Contingent Consideration is contingent upon achievement of the Triggering Events and is subject to offset as set forth in Section 1.6(f) below and that Parent’s obligations with respect to the Triggering Events are limited to those set forth in Section 11 hereof. The Company Stockholders acknowledge and agree that there can be no assurances that all or any of the triggering events will be reached or that all or any of the Contingent Consideration will, as a result, be paid.

(f) Right of Offset. Parent shall have the right to offset against any payment of the Contingent Consideration such amounts as set forth in Sections 9.3(c) and 12.1 hereof.

(g) Non-Transferability of Right. No Company Stockholder shall directly or indirectly sale, assign, gift, pledge, hypothecate, devise, bequest or otherwise voluntarily or involuntarily or by operation of law encumber, transfer or dispose of (each a “Transfer”) any of its rights or obligations, including without limitation, any right to receive any Contingent Consideration, under Section 1.6; provided, however, upon written notice to Parent and the Stockholder Representative, a Company Stockholder may Transfer its right to receive Contingent Consideration to any Affiliate of such Company Stockholder if such Affiliate is an Accredited Investor and otherwise agrees to be bound by the terms of the Stockholders Agreement and this Section 1.6(g). By their approval of the transactions contemplated by this Agreement, the Company Stockholders acknowledge and agree the foregoing. Any attempted Transfer in violation of this provision shall be null and void.

1.7 Closing of the Company’s Transfer Books. At the Effective Time, holders of certificates representing shares of Company Series A Preferred Stock, Company Series B Preferred Stock or Common Stock of the Company (the Company Series A Preferred Stock, the Company Series B Preferred Stock and the Common Stock is referred to as the “Company Stock”) that were outstanding immediately prior to the Effective Time shall cease to have any rights as stockholders of the Company, and the stock transfer books of the Company shall be closed with respect to all shares of such Company Stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of the Company Stock (a “Company Stock Certificate”) shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any of such shares of the Company Stock is presented by a Company Stockholder (as defined in Section 1.8 below) to the Surviving

Corporation or Parent, such Company Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.8.

1.8 Surrender or Exchange of Certificates. At or as soon as practicable after the Effective Time, but in no event later than five (5) days from the Effective Time, Parent will send to each individual and entity that was a stockholder of the Company immediately prior to the Effective Time (each a “Company Stockholder,” and collectively the “Company Stockholders”) (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify and (ii) instructions for use in effecting the surrender of the Company Stock Certificates in exchange for the relevant Merger Consideration as per Section 1.5. Upon surrender of a Company Stock Certificate to Parent for exchange, together with a duly executed letter of transmittal, each Company Stockholder shall be entitled to receive in exchange therefor the relevant Merger Consideration as per Section 1.5, and the Company Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.8, each Company Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive upon such surrender the relevant Merger Consideration as per Section 1.5. If any the Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion, and as a condition precedent to the issuance of any Merger Consideration, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an appropriate affidavit and indemnity against any claim that may be made against Parent or the Surviving Corporation with respect to such Company Stock Certificate.

1.9 Establishment of Escrow Fund. At the Closing, Parent shall withhold, from the amounts otherwise payable pursuant to Section 1 to the Company Stockholders, and shall deposit into an escrow fund (the “Escrow Fund”) with an escrow agent mutually acceptable to Parent and the Company (the “Escrow Agent”) on behalf of such holders, 1,494,600 of the Merger Shares (the “Escrow Amount”). The Escrow Fund shall be governed by the terms set forth in an escrow agreement in substantially the form attached thereto as Exhibit D (the “Escrow Agreement”) and the disposition of the Escrow Fund will be governed by the terms of this Agreement and the Escrow Agreement. Each Company Stockholder will be entitled to receive such Company Stockholder’s Pro Rata Share of any amounts that are released from the Escrow Fund to the Company Stockholders in accordance with the terms of this Agreement and the Escrow Agreement. “Pro Rata Share” means, with respect to each Company Stockholder, a fraction the numerator of which is the Merger Consideration to which such Company Stockholder is entitled under Section 1.5, and the denominator of which is the aggregate amount of Merger Consideration to which all Company Stockholders are entitled under Section 1.5.

1.10 Stockholder Representative. The Company Stockholders by virtue of the approval of this Agreement, (i) shall be deemed to have consented to the deposit of the Escrow Amount into the Escrow Fund pursuant to the terms of the Escrow Agreement, (ii) shall be deemed to have agreed that the Escrow Fund will be subject to the indemnification provisions of Section 9, and (iii) shall be deemed to have irrevocably constituted and appointed the Stockholder Representative (together with his or her permitted successors) as their true and lawful agent and attorney-in-fact to enter into the Escrow Agreement, to enter into any other agreement in connection with the transactions contemplated by this Agreement, to exercise all or any of the powers, authority and discretion conferred on the Stockholder Representative under this Agreement or any such agreement, to waive or amend any terms and conditions of this Agreement

or any such agreement, to give and receive notices on their behalf and to be their exclusive representative to the extent of their respective interests in the Escrow Fund with respect to any matter, suit, claim, action or proceeding arising with respect to any transaction contemplated by this Agreement or any such agreement, including the defense, settlement or compromise of any claim, action or proceeding for which a Parent Indemnified Person may be entitled to indemnification and the Stockholder Representative agrees to act as, and to undertake the duties and responsibilities of, such agent and attorney-in-fact. This power of attorney is coupled with an interest and is irrevocable. The Stockholder Representative, in connection with its obligations under this Agreement or any other agreement made in connection with the transactions contemplated by this Agreement, shall not be liable for any action taken or not taken or suffered by it in reliance upon any notice, direction, instruction, consent, statement or other document believed by it to be genuine and duly authorized, nor for any other action or inaction in the absence of his or her own gross negligence or willful misconduct. In all questions arising under this Agreement, the Escrow Agreement or any other agreement made in connection with the transactions contemplated by this Agreement, the Stockholder Representative may rely on the advice or opinion of counsel, and for anything done, omitted or suffered in good faith by the Stockholder Representative based on such advice, the Stockholder Representative shall not be liable to any Company Stockholder in its capacity as such. The Stockholder Representative shall have no duties or responsibilities other than those expressly set forth in this Agreement or the Escrow Agreement. The Stockholder Representative, acting as such under this Agreement, is not charged with knowledge of or any duties or responsibilities under, and shall not be bound by, any other document or agreement, other than the Escrow Agreement. If the Stockholder Representative shall be unable or unwilling to serve in such capacity, his or her successor shall be named by those persons who held a majority of the shares of Company Common Stock, on an as-if converted basis, held by all Company Stockholders immediately prior to the Effective Time and such successor shall serve and exercise the powers of Stockholder Representative hereunder.

1.11 No Fractional Shares. Notwithstanding anything to the contrary contained herein, no certificates representing fractional shares of any Parent Common Stock shall be issued hereunder. Each Company Stockholder who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all shares of Company Stock held by them) shall receive, in lieu thereof, case (without interest) in an amount equal to such fractional part of a share of Parent Common Stock multiplied by the Fair Market Value.

1.12 Restrictive Share Legend. All certificates representing Parent Common Stock to be issued hereunder shall bear a restrictive legend similar to the following legend, in addition to any other applicable legends required under state “blue sky” laws:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1993 (THE “ACT”), OR ANY STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED, SOLD, ASSIGNED, PLEDGED, OR OTHERWISE TRANSFERRED UNLESS REGISTERED OR QUALIFIED PURSUANT TO THE PROVISIONS OF THE ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO PARENT IS OBTAINED BY THE HOLDER OF THIS CERTIFICATE STATE THAT SUCH OFFER, SALE, ASSIGNMENT, PLEDGE OR TRANSFER IS EXEMPT FROM SUCH REGISTRATION OR QUALIFICATION.

The representations and warranties set forth in this Agreement shall survive thereafter as follows: (a) the representations and warranties of the Company set forth in Sections 2.1 (Due Organization; No Subsidiaries; Organizational Documents), 2.2 (Capitalization, Etc.) and 2.16 (Authority; Binding Nature of Agreement; Non-Contravention), and the representations and warranties of Parent and Merger Sub set forth in Sections 3.1 (Due Organization), 3.2 (Capitalization, Etc.) and 3.5 (Authority; Binding Nature of Agreement; Non-Contravention) (collectively, the "Fundamental Representations”), shall survive indefinitely; (b) the representations and warranties of the Company set forth in Sections 2.10 (Tax Matters) and 2.11 (Employee and Labor Matters; Benefit Plans) (collectively, the “Special Representations”), shall survive until the tenth day after the expiration of the applicable statute of limitations (as extended by agreement or otherwise) with respect to matters covered by those representations and warranties; and (c) all other representations and warranties set forth in this Agreement (the “General Representations”) shall survive until the date that is one (1) year following the Closing Date. No expiration of the survival of any representation or warranty shall in any way affect the survival of any other indemnity obligations contained in this Section 9, regardless of whether such indemnity obligations relate to matters also covered by representations and warranties. Notwithstanding the foregoing, if prior to expiration of the survival of any representation or warranty, a party seeking indemnification under this Agreement delivers a notice in accordance with the terms of this Agreement stating a claim of Damages, then the relevant representation and warranty shall survive, solely as to such claim as is asserted in the applicable notice until such time as such claim is finally resolved.

9.2 Indemnification.

(a) Indemnity by Company Stockholders. Subject to the conditions and provisions of this Section 9, the Company Stockholders shall indemnify, defend and hold harmless any Parent Indemnified Person from and against and in respect of all claims of Damages incurred by the Parent Indemnified Persons, directly or indirectly, by reason of or resulting from (i) any breach of any representation or warranty given or made by the Company in this Agreement; provided, that for purposes of determining any Parent Indemnified Person’s right to

indemnification hereunder, all qualifications in Section 2 relating to materiality and/or Material Adverse Effect shall be disregarded; and (ii) all Taxes of the Company relating to (A) any taxable period that ends on or before the Closing Date and (B) the portion of any Straddle Period ending at the end of the Closing Date as determined in accordance with Section 6.4(b).

(b) Indemnity By Parent. Subject to the conditions and provisions of this Section 9, Parent shall indemnify, defend and hold harmless any Stockholder Indemnified Person from and against and in respect of all claims of Damages incurred by such Stockholder Indemnified Person, directly or indirectly, by reason of or resulting from any breach of any representation or warranty given or made by Parent or Merger Sub in this Agreement; provided, that for purposes of determining any Stockholder Indemnified Person’s right to indemnification hereunder, all qualifications in Section 3 relating to materiality and/or Material Adverse Effect shall be disregarded.

9.3 Limitations.

(a) Threshold Amounts. Notwithstanding the other provisions of this Section 9, the Company Stockholders shall not be obligated to indemnify any Parent Indemnified Person with respect to any claim for Damages pursuant to Section 9.2(a)(i) unless and until the aggregate amount that the Parent Indemnified Persons are entitled to receive thereunder in the absence of this clause exceeds $42,000 (the “Stockholder Basket”). At such time that the aggregate amount recoverable by the Parent Indemnified Persons from the Escrow Fund exceeds the Stockholder Basket, the Parent Indemnified Persons shall only be entitled to recover the aggregate amount in excess of the Stockholder Basket (in no event shall the Company Stockholders be obligated to provide indemnification for any dollar amount below the Stockholder Basket). Notwithstanding the other provisions of this Section 9, the Parent shall not be obligated to indemnify any Stockholder Indemnified Person with respect to any claim for Damages pursuant to Section 9.2(b) unless and until the aggregate amount that the Stockholder Indemnified Persons are entitled to receive in the absence of this clause exceeds $42,000 (the “Parent Basket”). At such time that the aggregate amount recoverable by the Stockholder Indemnified Persons exceeds the Parent Basket, the Stockholder Indemnified Persons shall only be entitled to recover the aggregate amount in excess of the Parent Basket (in no event shall the Parent be obligated to provide indemnification for any dollar amount below the Parent Basket).

(b) Exclusivity of Remedies. The rights of any Stockholder Indemnified Person and Parent Indemnified Person to recover any amounts pursuant to this Section 9 shall be the sole and exclusive remedy of the Stockholder Indemnified Person and Parent Indemnified Person, respectively, for any breaches of any representation or warranty or provision of this Agreement and any other agreement entered into in connection with this Agreement or any claim against any Stockholder Indemnified Person or Parent Indemnified Person related to this transaction.

(c) Limitation of Damages (Company Stockholders). In no event shall any Company Stockholder be liable for any amount exceeding the net proceeds actually received by such Company Stockholder as part of such Company Stockholder’s Pro Rata Share of the Merger Consideration under this Agreement. Notwithstanding anything in this Agreement to the contrary, Parent’s (and any Parent Indemnified Person’s) sole and exclusive recourse against Company Stockholders with respect to any right to indemnification under Section 9.2(a)(i) in

connection with breaches of the General Representations and the Special Representations shall be as follows:

(i) The right to indemnification with respect to breaches of the General Representations in the aggregate shall be expressly limited to the Fair Market Value of the Merger Shares deposited in the Escrow Fund pursuant to Section 1.9 (the “General Representations Cap”), which may be satisfied through the Escrow Fund or as an offset to the Contingent Consideration as follows:

(1) The Parent Indemnified Persons shall first satisfy their indemnification rights with respect to breaches of the General Representations through recourse to the Escrow Fund.

(2) In the event that the Escrow Fund is insufficient to satisfy an indemnification claim with respect to a breach of the General Representations because the Parent Indemnified Parties have satisfied claims with respect to breaches of the Special Representations by obtaining payment from the Escrow Fund as provided in Section 9.3(c)(ii), then, subject to the General Representations Cap and Section 9.3(c)(iii), the Parent Indemnified Persons shall have the right to offset the payment of any Contingent Consideration then or thereafter due and payable by the amount of any such shortfall in the Escrow Fund.

(ii) The right to indemnification with respect to breaches of the Special Representations shall be satisfied as follows:

(1) The Parent Indemnified Persons shall first satisfy their indemnification rights with respect to breaches of the Special Representations through recourse to the Escrow Fund.

(2) In the event that the Escrow Fund is insufficient to satisfy an indemnification claim with respect to a breach of the Special Representations, then, subject to Section 9.3(c)(iii), the Parent Indemnified Parties shall have the right to offset the payment of any Contingent Consideration by the amount of any such shortfall in the Escrow Fund.

(iii) Notwithstanding anything contained in Sections 9.3(c)(i) and (ii), the ability of the Parent Indemnified Parties to offset the payment of the Contingent Consideration under Section 9.3(c) shall be limited to 15% of the amount of the Contingent Consideration otherwise due to the Company Stockholders at such time. In the event that the amount of offset is insufficient to satisfy fully indemnification obligations of the Company Stockholders as provided in this Section 9.3, the Parent Indemnified Parties shall have the right to offset any subsequent payments of Contingent Consideration by the amount of such shortfall.

(iv) For purposes of satisfaction of indemnification claims through recourse to the Escrow Fund, Merger Shares held in the Escrow Fund shall be valued at the Fair Market Value.

(d) Limitation of Damages (Parent) Notwithstanding anything in this Agreement to the contrary, the Company Stockholders’ (and any Stockholder Indemnified Person’s) sole and exclusive recourse against Parent with respect to any right to indemnification

hereunder or other claims arising after the Closing with respect to the Merger or otherwise arising under or with respect to this Agreement shall be in the aggregate expressly limited to $3,183,498.

9.4 Indemnification Procedures.

(a) General. A person seeking indemnification under this Section 9 (the “Indemnitee”) shall give prompt written notice to party from whom indemnification is sought hereunder (the "Indemnifying Party”) of any claim of Damages which is asserted against, resulting to, imposed upon or incurred by such Indemnitee and which may give rise to liability of the Indemnifying Party pursuant to this Section 9, stating (to the extent known or reasonably anticipated) the nature and basis of such claim and the amount thereof. The timely delivery of such written notice by the Indemnitee to the Indemnifying Party shall be a condition precedent to any liability on the part of the Indemnifying Party under this Section 9 with respect to such claim of Damage.

(b) Defense of Non-Tax Third Party Claims. Subject to Section 9.4(c), the Indemnifying Party shall have the right, at its option, to assume the defense using its own counsel of any claim or action brought by any third party that may give rise to an indemnification right of any party hereto. If the Indemnifying Party elects to assume the defense of any such matter, then:

(i) notwithstanding anything to the contrary contained in this Agreement, the Indemnifying Party shall not be required to pay or otherwise indemnify the Indemnitee against any attorneys’ fees or other expenses incurred on behalf of the Indemnitee in connection with such matter following the Indemnifying Party’s election to assume the defense of such matter;

(ii) the Indemnitee shall make available to the Indemnifying Party all books, records and other documents and materials that are under the direct or indirect control of the Indemnitee or any of the Indemnitee’s officers, directors, employees or agents, and that the Indemnifying Party considers necessary or desirable for the defense of such matter;

(iii) the Indemnitee shall execute such documents and take such other actions as the Indemnifying Party may reasonably request for the purpose of facilitating the defense of, or any settlement, compromise or adjustment relating to, such matter;

(iv) the Indemnitee shall otherwise fully cooperate as reasonably requested by the Indemnifying Party in the defense of such matter;

(v) the Indemnitee shall not admit any liability with respect to such matter; and

(vi) the Indemnifying Party shall have the exclusive right to settle, adjust or compromise such matter, on such terms as it may deem appropriate, without the consent or approval of the Indemnitee or any other person or entity, provided, that any such settlement without consent or approval contains an unconditional release of the Indemnified Party.

(vii) In the event that the Indemnifying Party fails or elects not to or is not entitled to assume the defense of the Indemnitee against any third party claim, then the Indemnitee shall have the right to undertake the defense, provided, however, that the Indemnitee shall not compromise or settle such third party claim or consent to entry of any judgment in respect thereof without the prior written consent of Indemnifying Party, which shall not be unreasonably withheld. In each case, the Indemnitee shall conduct the defense of the third party claim actively and diligently, and the Indemnifying Party will cooperate with the Indemnitee in the defense of that claim and will provide full access to documents, assets, properties, books and records reasonably requested by the Indemnitee and relevant to the claim and will use their commercially reasonable efforts to make available all individuals reasonably requested by the Indemnitee for investigation, depositions and trial.

(c) Defense of Tax Claims. The Indemnifying Party may elect to control, and may elect to have sole discretion in handling, settling or contesting any audit inquiry, information request, audit proceeding, suit, contest or any other action with respect to a Tax controversy for which it would be required to indemnify the other party if it acknowledges in writing that it has sole liability for any Taxes that might arise in such proceeding and agrees in writing to indemnify, defend and hold harmless the Indemnitee from and against and in respect of any such Taxes without regard for the limitations set forth in Section 9.3 (any such Tax controversy, a “Directed Tax Controversy”). The Indemnifying Party shall not compromise or settle any proceeding with respect to a Tax controversy without obtaining the Indemnitee’s prior written consent if such compromise or settlement would have the effect of increasing any Tax liability of the Company or otherwise adversely affecting any Tax attribute of the Company, in each case for any taxable period ending after the Closing Date. If the Indemnifying Party chooses to cause a Tax controversy to become a Directed Tax Controversy in accordance with the first sentence of this Section 9.4(c), the Indemnitee shall cause to be delivered to the Indemnifying Party powers of attorney authorizing the Indemnifying Party to represent the Company before the relevant taxing authority and such other documents as are reasonably necessary for the Indemnifying Party to control the conduct of such Directed Tax Controversy, consistent with the terms of this Section 9.4(c). The parties shall jointly control, and shall each have the right to participate in all activities and strategic decisions with respect to, any Tax controversy that is not a Directed Tax Controversy.

For all purposes under this Section 9.4, if the Indemnifying Party is deemed to be the Stockholders, then all notices to and from the Indemnifying Party shall be made to and from the Stockholder Representative, and all rights of the Indemnifying Party hereunder shall be held by the Stockholder Representative.

9.5 Characterization of Indemnity Payments. The Parties hereto agree that any indemnification payment made pursuant to this Agreement shall be treated as an adjustment to the Merger Consideration for all Tax purposes.

SECTION 10. Termination

10.1 Termination Events. This Agreement may be terminated at any time before the Closing Date under any one or more of the following circumstances:

(a) Parent and the Company may terminate this Agreement by mutual written consent; or

(b) Parent may terminate this Agreement at any time prior to the Effective Time (i) in the event the Company has breached any material representation, warranty, or covenant contained in this Agreement in any material respect, Parent has notified the Company of the breach, and the breach has continued without cure for a period of 15 days after the notice of breach or (ii) if the Closing does not take place on or before January 31, 2006 by reason of the failure of any condition precedent under Section 7, unless such failure results from Parent’s or Merger Sub’s failure to comply with or perform in any material respect any covenant under this Agreement; or

(c) The Company may terminate this Agreement at any time prior to the Effective Time (i) in the event Parent has breached any material representation, warranty, or covenant contained in this Agreement in any material respect, the Company has notified Parent of the breach, and the breach has continued without cure for a period of 15 days after the notice of breach or (ii) if the Closing does not take place on or before January 31, 2006 by reason of the failure of any condition precedent under Section 8, unless such failure results from Company’s failure to comply with or perform in any material respect any covenant under this Agreement.

10.2 Effect of Termination. If this Agreement is terminated pursuant to Section 10.1, all further obligations of the parties under this Agreement shall terminate and all materials provided by the Disclosing Party shall be immediately returned by the Receiving Party (as defined in Section 11.4), or the Receiving Party shall certify to the Disclosing Party that such materials have been destroyed; provided, however, that: (a) neither the Company nor Parent shall be relieved of any obligation or liability arising from any prior breach by such party of any provision of this Agreement; and (b) the parties shall, in all events, remain bound by and continue to be subject to the provisions set forth in Section 11.4.

SECTION 11. Diligence Obligations

11.1 Development and Commercialization of Company Products. Parent shall itself or through its Affiliates or sublicensees use Commercially Reasonable Efforts in the development of at least one HDAC Inhibitor and at least one Aurora Kinase Inhibitor. For purposes of this Section 11.1, "Commercially Reasonable Efforts” shall mean the efforts and resources used by bio-pharmaceutical companies similarly situated as Parent, consistent with generally-accepted industry standards, with regard to the development, manufacture and commercialization of pharmaceutical products of similar market and profit potential at a similar stage in development or product life, taking into account all factors that impact the manufacturing, development, marketing and sales of such products, as applicable. It is understood that the potential of any product in development may change from time to time based upon changing scientific, business, marketing, resource and return on investment considerations. The exercise by Parent of Commercially Reasonable Efforts is to be determined by judging its efforts taking into account all of these factors..

SECTION 12. Miscellaneous.

12.1 Fees and Expenses. Except as otherwise provided herein, Parent shall pay all of the fees, costs and expenses (including fees, costs and expenses of legal counsel, investment bankers, brokers or other representatives and consultants and appraisal fees, costs and expenses) incurred in connection with the negotiation of this Agreement by any party hereto (the “Fees”) and the other agreements contemplated by this Agreement, the performance of its obligations hereunder and thereunder, and the consummation of the transactions contemplated hereby and thereby. At least two (2) business days prior to the Closing, the Company shall deliver to Parent final invoices for all Fees incurred by the Company. Any such Fees in excess of $1.25 million will result in reduction of the number of Merger Shares to be issued in the Merger on a dollar for dollar basis based on the Fair Market Value. With respect to any Fees not included in the final invoices referred to above in excess of $1.25 million in the aggregate, Parent shall have the right (i) to receive from the Escrow Fund the amount of any such Fees and (ii) to exercise its right to offset set forth in Section 1.6.

12.2 Disclosure Schedules. Each of the Company Disclosure Schedule and the Parent/Merger Sub Disclosure Schedule (each, a “Disclosure Schedule”) has been arranged, for purposes of convenience only, as separate parts corresponding to the sections of Section 2 or Section 3, respectively. Any information set forth in any part of a Disclosure Schedule shall be deemed to be disclosed and incorporated by reference in each of the other parts of the Disclosure Schedule as though fully set forth in such other parts (whether or not specific cross-references are made) and shall be deemed to qualify and limit all representations and warranties of the Company or the Parent or Merger Sub, as applicable, set forth in this Agreement, provided that such deemed disclosure would be appropriate and reasonably apparent on the face of the actual disclosure without reference to the underlying document or information. No reference to or disclosure of any item or other matter in a Disclosure Schedule shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in a Disclosure Schedule. The information set forth in a Disclosure Schedule is disclosed solely for the purposes of this Agreement, and no information set forth therein shall be deemed to be an admission by any party hereto to any third party of any matter whatsoever, including of any violation of Law or breach of any agreement.

12.3 Notices. Any notice or other communication required or permitted to be delivered to any party under this Agreement shall be in writing and shall be deemed properly delivered, given and received (a) when delivered by hand, or (b) the first business day after sent by registered mail, by courier or express delivery service or by facsimile, in any case to the address or facsimile telephone number set forth beneath the name of such party below (or to such other address or facsimile telephone number as such party shall have specified in a written notice given to the other parties hereto):
